Seed saga round 2: Passiflora quandrangularis, or the giant granadilla passionflower. One of my favourite tropical climbers with the most amazing huge flowers! This one has to be soaked in orange juice to degrade the seed coating - mimicking the acidic passionfruit juices it would naturally soak up. #seedsaga#passiflora#passionfruit#exotics#jungleseeds#bristolaquarium
